Subject [jira] [Commented] (HDFS-10828) Fix usage of FsDatasetImpl object lock in ReplicaMap
Date Tue, 27 Sep 2016 02:06:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15524786#comment-15524786

Fenghua Hu commented on HDFS-10828:


Actually, i opened another JIRA https://issues.apache.org/jira/browse/HDFS-10804 for replicaMap
lock issue, but after seeing your fix, i thought we could consider them together in HDFS-10828.

I agree with you that it makes sense to keep the existing behavior in this fix, and we will
use HDFS-10804 to track ReplicaMap issue.  Thanks.
